One of the efforts to increase the production of tiger shrimp Penaeus monodon is increasing the immune response against WSSV disease. This study aims to evaluate shrimp immune response to dsRNA VP-24 vaccination at various doses. The construction of dsRNA VP-24 vaccine was performed using Megascript kit with the VP-24 DNA genome as a template. The vaccination was done by injection method on shrimp sized 15.88 ± 3.50 g. The tested vaccine doses (treatments) were 0.02 ¼g; 0.2 ¼g; 2 ¼g; and unvaccinated shrimp as the control. The study consisted of four treatments of vaccine doses with two replicates for each treatment. The challenge test was performed by injecting the WSSV virus in saline solution (1:3 v/v). The observation on shrimp survival rate was done daily, while the total hemocyte count (THC) and ProPO observation were performed on the 1st day, 3rd day, and 6th day after WSSV infection. At the end of the experiment, samplings of hepatopancreas for analysis were performed. Data were statistically analyzed using ANOVA. The present study indicated that the injection of 0.2 ¼ g dsRNA VP-24 vaccine had a significant effect on the survival rate and immune response of shrimp (P<0.05). The dose of 0.2 ¼g dsRNA VP-24 had resulted in 65% of survival rate and increased immune response of P. monodon with THC (1,550 x 10t cell/mL) and ProPO (0.042 Abs).
